Hey, I just made this account just to add that I also have the same problem with mine. I never saw a spring or something that sort fly off. In fact I don't even see where one could be located on this tiny latch. How can we repair this since it's irritating handling the grip this way. The sound alone this flappy little latch makes is so annoying.
I just upgraded from a X-T2 to a brandneue X-T4 and compared to my old camera the lens release button feels just a little bit stiff/not so easy to press when a lens is mounted. without a Lens mounted the button can be pressed seemlessly. May I ask if that‘s normal?
But... You can't monitor audio and power the camera from the same usb port. I've tried several splitter options and none of them work; leaving me to monitor audio with their usb dongle and pull that if I have to power the camera with my monitor battery usb out.
When shooting video a camera is fully caged, with matte box, rails and follow focus. You don't want to change a battery out. You pretty much have to tear down your rig to do that...
